Not to mention the various aluminum materials, it is not possible to develop in a short period of time, even if it is studied according to this reference material, it is not possible to successfully test in a short period of time. Even if the test is successful, it will take a long time from success to molding.

What's more, whether it is a fighter or a transport aircraft, in addition to materials, there is also one of the most critical core technologies, the engine. That is the most lethal technical barrier, the engine can't be developed, and building the aircraft yourself is just a dream.

However, Li Yunlong can't deliberately hit Hang Zhiyuan, not to mention, wouldn't it be cooler if the system can jump out of a drawing of an aircraft engine?

Of course, Li Yunlong will not give Hang Zhiyuan a chance to fantasize in advance, everything depends on whether this system is really powerful.

I was worried that Ding Wei was undergoing the harshest test, even if the most bitter cold weather had passed now, but on the desert Gobi in the Ganning region, there would still be no good environment to speak of. So the day after rescuing Tian Yulai, Li Yunlong set off with people.

Li Yunlong didn't bring many people, one is that the manpower on the side of the reinforced battalion is not very sufficient, and he has to take on the heavy responsibility of defending the military factory. On the other hand, there are more people to bring, and eating and drinking on the road are all problems, and Li Yunlong also wants to bring more weapons and equipment to be more cost-effective.

So Li Yunlong only brought five people, and Zhang Dabiao was the first to follow him, and he was the most reliable in terms of ability and trust. Yang Shishi and Wei Dayong are also their right-hand men, and it is not too much to top ten.

Duan Peng's ability during this period of time is very strong, and his progress is also extremely fast, and he has surpassed Wei Dayong, because of Duan Peng's appearance, Wei Dayong also has the strength to catch up, and it is not a bad thing for the two of them to work so hard.

Only Liu Sanxi, Li Yunlong didn't think about taking this kid with him at first, but this guy insisted on following Li Yunlong, and when he thought of Liu Erdan at the beginning, Li Yunlong had no choice, so he nodded and agreed.

Crossing the western Shanxi and central Shanxi provinces, six people and eight horses walked for more than ten days before they came to the border area of the Ganning region.

The scene in the Ganning area gives people the first feeling of desolation.

When Li Yunlong set off, the Taihang Mountain was already full of green, although it had not yet reached the level of green mountains, but the plants all over the mountains had sprouted and spit green.

Along the way, the surrounding colors are getting lighter and lighter, and when you come to the border of Gansu and Ningbo, you can only occasionally see a few treetops with green poplars, and the plants in the surrounding sand only glow a little bit of yellow, the farther away from the eastern region, the more light the spring will be.

On the way, Li Yunlong also roughly understood everything about Gan Ning's side.

The Third Regiment led by Ding Wei was subordinate to the Second Brigade in the Ganning area, and the situation here was more complicated than that in the western part of Jinxi.

The Ganning region already belongs to the northwest, and both the grain output and the climate are not suitable for the growth of grain crops, and the lives of the common people are poorer.

Many people who have no food to eat have gradually turned into bandits who rely on robbery to survive, Ganning is mostly desert Gobi, and some are located in the Loess Plateau, where villages are scarce, these bandits are gradually equipped with a large number of horses, these bandits are gradually getting bigger, and they run away after grabbing, even if they are the army of the Japanese country, they have no temper with these horse bandits who are as fast as the wind.

So much so that these horse bandits are getting bigger and bigger, and they have gradually become the most troublesome existence in the entire Ganning area.

Even on the way here, several Eighth Route garrisons adjacent to the Ganning area reminded Li Yunlong that the Third Regiment led by the location was probably hiding in the depths of the Gobi Desert because of a conflict with the Ma Gang.

"Stop!"

Li Yunlong waved his hand and shouted to stop everyone.

"Captain, what did you find?"

Yang Shi's title for Li Yunlong was also changed to captain with the change of Li Yunlong's position.

Li Yunlong was happy, "There are two people staring at us from a distance!" ”

"Where?"

Wei Dayong was just about to turn his head to look, but was immediately stopped by Li Yunlong.

"They are all looking around, they must have taken a fancy to our immediate supplies. Hehe, it looks like I've met an opponent this time! ”

"Are there any devils?"

"This is not necessarily, it looks like a devil, but depending on the proficiency of the other party in horseback riding, it doesn't look like a devil."

The other party only had two horses, and Li Yunlong also glanced at it quietly, because the distance was too far away, and the other party did not speak, Li Yunlong couldn't figure out where the two people came from for the time being.

However, the identities of the two people can be roughly guessed, and it should be spies sent by which team.

Wei Dayong whispered, "Captain, why don't you stay, sneak down, teach these two guys a lesson, and ask who it is by the way?" ”

Li Yunlong sneered, "No, this place is less than twenty miles away from Jiading City, we don't need to do it with others in this kind of place, once we do it, our materials will suffer losses, it's not cost-effective!" ”

"Jiading City seems to be the realm of three things, right?"

Zhang Dabiao, who had been silent, suddenly said.

Li Yunlong smiled, "Yes, Jiading City is too small to accommodate the garrison at all, so even the little devils will not choose to be stationed there, and our team of the Eighth Route Army does not want to put our team in such a conspicuous place, so this place has become a place where there are no three things, and it is very chaotic." ”

Although Li Yunlong said this, this kind of place where the three things don't matter is the most dangerous, but for Wei Dayong and the others, they are very much looking forward to it.

The more places like this, the more valuable news you can hear.

Even if Li Yunlong wanted to get some more clues about Ding Wei's team, he had to go to Jiading City.

"Let's go, don't worry about those two spies, if nothing else, the forces behind these two guys will show up at night, let's not rush!"

Li Yunlong didn't look back, his legs clamped, urging the war horse forward.

If it weren't for the purpose of carrying those two bazookas, Li Yunlong would not have arranged two more batches of war horses to transport materials, although it was a bit risky to do so, but for the severe challenges that will be faced next, these two bazookas are very necessary and important weapons and equipment.

Although Li Yunlong wrapped a lot of things around the outside of the two bazookas, this shape really can't be concealed, as long as he is knowledgeable, he can basically distinguish it at a glance.

Now that there are spies appearing, this means that the other party has already set their eyes on him, and he is unwilling to give up when he sees that he is carrying a bazooka, and it will be a big trouble tonight.
